1. A computer-implemented method, comprising:
capturing, by one or more processors, using one or more sensors of an Augmented Reality (AR) system, sensor data of forces acting on a frame of the AR system, the one or more sensors comprising one or more respective sensing surfaces aligned with a frame hinge leaf surface of the frame;
generating, by the one or more processors, a corrected frame model of the frame based on the sensor data and a physical model of the frame;
capturing, by the one or more processors, using one or more imaging devices mounted on the frame, tracking video frame data of one or more physical objects in a real-world scene viewed by a user of the AR system;
capturing, by the one or more processors, using a pose component of the AR system, pose and location data of the AR system as the AR system is capturing the tracking video frame data; and
generating, by the one or more processors, tracking data based on the corrected frame model, the tracking video frame data, and the pose and location data.
